ART DPSII Digital Preamplifier System with Variable Valve Voicing.
Add texture to any audio source! These two-channel high performance preamps use a hand selected 12AX7A tube in the low noise input circuitry. This, coupled with ART's proprietary V3™ (Variable Valve Voicing) and variable input impedance allow the TPS II and DPS II to deliver incredible performance from cost effective single space rackmount solutions.
In the case of the DPS II, the added convenience of direct digital output connectivity making it an ideal expander for any computer interface or sound card with RCA S/Pdif digital input.
V3 Technology
V3™ provides optimized reference points to begin the recording process. The
V3™ presets were created and fine-tuned by some of the industry's top studio
and live-sound engineers. V3™ technology allows you to select between a
multitude of presets designed for guitars (electric and acoustic), keyboards,
bass guitars, drums, vocals and more.
Variable Input Impedance
Variable input impedance increases the sonic potential of the TPS II & DPS
II even further. It delivers entirely new sonic textures and tone by varying the
input impedance of the preamp, which in turn varies the way the microphone
reacts to the load of the preamp. This creates a wide range of new sonic
possibilities with any modern or vintage condenser, ribbon or dynamic
microphone.
The variable impedance control is infinitely variable allowing much finer control and the ability to tune the preamp to the microphone's ideal sweet spot. A feature usually only available on far more expensive and exclusive microphone preamps.
Extremely Wide Dynamic Range
The DPS II and TPS II can accept up to +20dB peaks while maintaining over 120dB
dynamic range with incredibly low distortion. Input LED metering monitors the
signal level of the input amplifier so maximum gain can be achieved without
clipping the preamp at the input.
OPL (Output Protection Limiter)
ART's OPL™ (Output Protection Limiter), which precisely and accurately
controls and maintains the output peak signal. The OPL™ circuitry is crucial
in protecting the next link in a signal chain – such as a hard-disk recording
system or a sound card – because unlike analog clipping that sounds musical
and sometimes pleasing, digital clipping is nasty and often fatal for your
monitors' tweeters.
Digital Connectivity (DPS II)
Digital outputs include S/PDIF, TOSLINK or ADAT (front panel selectable). The
A/D is front panel adjustable from 44.1 to 96K or syncs to ADAT or external
word clock (32KHZ to 100KHz). Multiple DPS II's can be added to an ADAT
stream.
A versatile insert loop on each channel provides access for additional signal processing or direct access to our high quality A/D converter. Separate gain controls on analog and digital outputs allow you to optimize the unit for simultaneous applications.
